| 摘 要： | 在对比研究煎茶岭大型镍矿与金川超大型镍矿的矿床地质球化学特征基础上，对两个矿床中的伴生金与镍及超基性岩的成矿关系进行了分析比较，两区不同的构造环境控制了超基性岩的不同分布。两矿床中的Ｎｉ、Ａｕ均来自超基性岩，且Ｎｉ矿床中金均为伴生矿，金川伴生金的丰度与镍成正比，而煎茶岭Ｎｉ矿中僮生金的丰度与镍成反比，其原因可能与各自不同的成矿环境及岩浆活动有关，尽管两镍矿中金的成矿机理基本相似。

| Abstract: | On the basis of comparative studying on the characteristics of geology and geochemistry of Jinchuan superlarge nickel deposit and Jianchaling large nickle deposit,the metallogenic relation of the associated gold to nickel and ultrabasic rock in the two deposits is comparatively analysed The different structural enviornments of the two regions controls the different distribution of ultrabasic rock The gold and nickel of the two deposits all come from the ultrabasic rock and all are the associated gold ore in both deposits; and the abundance of gold is in direct proportion to that of nickel in Jinchuan deposit, whereas the abundance of gold is in inverse proportion to that of nickel in Jianchaling deposit The reason of differences could relate to different metallogenic enviornments and magma activities, although the metallogenic mechanism of gold in the two deposits is mainly similar |
